There are four sentences that fall in series in Will McCants’s Conclusion — three of a kind followed by one with a different quality to it. Each one ends a section, and the last ends the Conclusion as a whole:

This is not Bin Laden’s apocalypse.

This is not Bin Laden’s insurgency.

This is not Bin Laden’s caliphate.

This may not be Bin Laden’s jihad, but it’s a formula future jihadists will find hard to resist.
